She took longer than you would usually expect to reply, but by her reaction, she clearly didn’t get the implied sarcasm. Well, not really sarcasm, but you meant it to sound that way, mostly so she didn’t worry. Well, that plan’s down the ablution trap now. You type back.

At this point you really have no idea what your emotions are doing, or rather why they are causing you to cry. It was a matter of sense and self-preservation. He had to die, it wasn’t your fault, you were protecting yourself and those around you by ending his life.

TT: Can you tell me what's wrong, and how I can help? I'm happy to talk, but first I need to know what I can do for you.
You type back worriedly and as quickly as you’ve heard her piece, trying to make sure she knows that you’re here for her if she needs it. And it looks to be like she really needs it.
